Flies for Rivers - Scorpion Dun (Trico - Size 22)


What I see most clearly of all is a reflection of the hookpoint back against the mirror of the water's surface. This can be very conspicuous, and I suppose it accounts for many of the trout's refusals of artificial flies.  — Datus C. Proper, What The Trout Said

The first inverted mayfly that works, the Scorpion Dun offers a solution to the most discerning trout.  Our flagship pattern overcomes design flaws common to other upside-down flies in resolving Datus Proper's "mirrored hook" quandry.

Unlike standard ties, Scorpion's abdomen curves upward to ride like a natural. The hook typically sets in the upper jaw, enhancing angler control and the likelihood of quick release. A twisted-CDC underbody aids in floatation, and a "hackle harness" supplies stability and a natural silhouette. The hook's bend and point remain above water, invisible from below.

Scorpion Duns land correctly, appear realistic, and consistently fool trout that refuse even the best orthodox patterns.

Offered in size 22 for mayflies with significant adult stages.

Client Testimonial:
"I had never tried any upside-down dun or spinner patterns, but this season Buck keyed me into a fish's perspective when surface feeding and the advantage of hiding the hook's profile from picky fish. His Scorpion patterns consistently produced on highly selective fish, in my opinion due to the silhouette of an arched tail and realistic fluttering wing.  I'm convinced the angle from the inverted hook leads to more solid top-jaw hookups, and I know the short-shank Tiemco hooks helped me land more fish - even the smallest sizes do not straighten on big fish. Several waters I fish in the late summer tend to weed up pretty badly. It was noticeable how the inverted hook rarely snagged when I re-cast over a fish, where I was having to clean traditional patterns after every cast. Buck is the only tier I know that offers this style mayfly pattern."
